Application filed November 27, 1915. Serial No. 63,784.

To all whom it may concern:

Be it known that l, ALVA D. JONES, a citizen of the United States,residing in the .city' and county of Philadelphia and State ofPennsylvania, have invented a new and useful Non-Resonant Music-Cabinet,Particularly Adapted to be Used in Talking-Machines and other SoundInstruments, of which the following is a specification.

My invention relates to a novel construction of a talking machinecabinet, being formed of a non-resonant substance and preferably madefrom ratan, willow, or other reed substances.

It is a well known fact that the musical vibrations occurring in thetalking machine as well as piano, are greatly marred by sympathizing andexciting to vibratory movement the supporting frame and body portion ofthese instruments. This. is particularly undesirable in the case of thetalking machine as this instrument has to deal with the reproduction ofthe human voice, the tonal quality of which is greatly varied inaccordance with the various board parts of this instrument as it hasbeen constructed in the past. After exhaustive tests][ have found thaton reproducing records of various tonal qualities and pitch, that onplacing my hand on the wood parts of this instrument, the

wood vibrates to a. very considerable degree, v

and that the various sounds coming from the record sympathize withvariousboards going to make up this cabinet. For example, a

very high pitch will sympathize with a certain board,-a very low pitchwith a dinerent tonal quality will sympathize with a separate panel ofthe wood work depending upon whether this particular panel or board y isto a greater degree in sympathetic vibratory accordance with arespective sound coming from the record. The above facts are well knownand it is useless to exhaustibly detail the various sympatheticrelations which 5 are known to exist between resonant vibratoryelements, but in my new construction of a talking machine cabinet, lhave used a nonreso'nant but yet vibratory substance, which is notcapable of changing the speed of vibra- 5e tions coming from the recordor in any way adulterating them. In accomplishing this function in atalking machine cabinet, I have found that reed, properly plaited' orwoven is extremely attractive, light, and more durable than wood of theboard formation.

My invention further consists of other Specification of Letters Patent.

tion is not limited to the precise arrange- .my talking machine cabinet,which body r mmed ne no, rare.

novel features, all as will hereinafter be fully set forth.

For the purpose of illustrating my invention I have shown inaccompanying drawings, one form thereof, which is at present preferredby me since the same will be found to give absolute satisfaction andreliable. results inpractice, although it is to be understood that thevarious instrumentalities of which my invention consists may bevariously arranged andorganized, and that my invenment and organizationof these instrumentalities as herein shown and described.

*Figure 1 is a plan view of my new con-' struction of a talking machinecabinet taken through the central portion of said cabinet, showing themotor and turn table mounted on a plaited non-resonant ledge. Fig. 2shows a side elevation of my new talking machine cabinet, partly insection, showing a motor and turn table mounted thereon.

Referring to the drawings, 1 represents a part of the body portion of mynon-resonant talking machine cabinet, 2 represents an inwardly extendingledge made of plaited material having the function of being nonresonantupon which is mounted the frame work 3 which supports the motortable 4,which has mounted upon it a turn table 5.

Fig. 21 represents the body portion of portion carries the ledge 2 whichsupports the frame 3, which has mounted upon it the frame work t whichcarries the turn table 5 and the motor 6. a

I do not wish to limit my novel nonresonant cabinet to any particularuse, as the same may be extremely useful in piano construction, or thesupporting stand of a telephone, and I therefore reserve the right touse this sort of a construction in any acoustical instrument, wherein 'asympathetic resonant substance is undesirable, in conjunction withsound.

In Fig. 2, l have indicated, partly by dotted lines, a typicalsound-box, tone-arm and horn, it being understood that any conventionalor desired construction of such partsmay be employed.

As I am the first in'the art to produce a talking machine, support, caseor cabinet incapable of sympathetic sound vibration, or, in other words,having no inherent fundamental tone of its own, and preferably made fromreed, ratan, cane, willow, wicker,

arm, turn table,

2. The combination with the reproducingmechanism of a talking machine,of a support and inclosure therefor composed of plaited or woven reed,.ratan, cane, or similar elements and incapable of sympathetic soundvibration. p

3. The combination with a talking machine, of a cabinet for said talkingmachine inclosing the latter and composed of reed, ratan, cane orsimilar elements associated in such a manner as to form a cabinetbodyincapable of sympathetic sound vibration.

4. The combination of a cabinet having no inherent fundamental tone, andcomposed of reed, ratan, ments, and sound within the cabinet.

5. The combination of a cabinet having no fundamental tone of its own,composed of reed, cane ratan, cane or similar elements, and providedwith a ledge havin no fundamental tone of its own, of soun reproducingmechanism supported on said ledge.

6. The combination with sound reproducing mechanism, of a cabinet havingits side walls formed of reed and provided with means within said sidewalls to support the sound reproducingmechanism.

7. The combination with a talking machine, of a case therefor, compo. edof reed, ratamcane or similar elements, and having no inherentfundamental tone of its own, said case having a sound exit therefrom.

8. The combination with a talking machine, of a case therefor, composedof reed, ratan, cane or similar elements, and having no inherentfundamental tone of its own, said case having a sound exit inclosedwithin it.
